Petrobras announces that its proven reserves in the pre-salt in 2013 grew by 43% when compared to 2012. Since 2007, the company has been incorporating growing volumes to its proven reserves from the pre-salt layer, which stretches from southern Espírito Santo state to Santa Catarina state. Currently, more than one-quarter of Petrobras’ proven reserves comes from the pre-salt. This 43% reserves growth in 2013 was possible due to the drilling of 42 wells in the pre-salt, combined with the excellent performance of the platforms in production at Campos and Santos Basins.
It is worth noticing that this reserve increase is taking place at the same time that pre-salt production grows. On January 13, 2014 the second production well of platform Cidade de Paraty, at Lula field, went into operation, with an output of 28 thousand barrels of oil per day, totaling 58 thousand barrels of oil per day on this platform.
As a result, a new daily record was set on January 14, 2014, in which oil production operated by Petrobras in the pre-salt surpassed 390 thousand barrels of oil per day. The previous record of 371 thousand barrels of oil per day was set on December 24, 2013.
Of the two basins producing from the pre-salt, Campos and Santos, the latter contributed with 51% of this record of 390 thousand barrels of oil per day, through nine production wells, confirming the high productivity of the pre-salt fields. The average productivity of the commercial wells in the Santos Basin pre-salt has been around 25 thousand barrels of oil per well per day, higher than that of the North Sea (15,000 barrels of oil per well per day) and the Gulf of Mexico (10,000 barrels of oil per well per day).
The accumulated production for the pre-salt fields, beginning in 2008, has already surpassed 290 million barrels of oil equivalent. Therefore, in 6 years of pre-salt production, we have already produced almost twice of what we have produced in 35 years at Garoupa field (156,000,000 barrels of oil equivalent), located in Campos Basin.
In December of 2013, three Declarations of Commerciality proved the production feasibility in three different pre-salt areas: Lapa (Carioca), Búzios (Franco) and Sul de Lula (Sul de Tupi), all in Santos Basin.
In addition, in 2013, pre-salt discoveries in fields already in production in Campos Basin, such as Albacora, Caratinga and Marlim Leste contributed to the growth in reserves, and, primarily, to their swift monetization by interconnecting wells to the platforms in operation.
Another significant result and that sustains the planning of future production in pre-salt areas is its excellent exploratory success, which was 100% in 2013, that is, all of the pre-salt wells drilled in 2013 indicated the presence of hydrocarbons.
In 2014, 17 new wells will be interconnected to already installed platforms in the Santos Basin pre-salt.
In the second half of 2014, two new platforms will go on stream in the Santos Basin pre-salt: platform Cidade de Ilhabela in Sapinhoá Norte field, and platform Cidade de Mangaratiba in Iracema Sul field, adding 300 thousand barrels of oil per day in installed capacity. Five new wells will be interconnected to these new platforms in 2014.
The start-up of these two new platforms (Cidade de Ilhabela and Cidade de Mangaratiba) and the start-up of 22 new production wells in 2014 will contribute to the achievement of new pre-salt production records in 2014.
